Basic concept 1.系统( Thermodynamic Systen):A quantity of matter or a region in space chosen for study. (系统就是指被选做研究对象的物体或空间。) 2.平衡状态( Equilibrium State) A system in equilibrium experiences no changes with time when it is isolated from its surroundings 所谓平衡状态就是指在没有外界影响的情况下,系统 的状态不随时间而发生变化

3准静态过程( Quasi- static process) 在无限小势差推动下的由连续平衡态组成的过 程,就是准静态过程。 When a process proceeds in such a manner that the system remains infinitesimally close to an equilibrium state at all times, it is called a quasi- static or quasi-equilibrium process
3 .准静态过程 (Q u a s i -s t a t i c P ro c e s s ) 在无限小势差推动下的由连续平衡态组成的过 程，就是准静态过程。 When a process proceeds in such a manner that the system remains infinitesimally close to an equilibrium state at all times, it is called a quasistatic or quasi-equilibrium process
4.可逆过程( Reversible process) 系统经历某一过程后,如果能使系统与外界同时恢 复到初始状态,而不留下任何痕迹,则此过程为可 逆过程。 A process that can reversed without leaving any trace on the surroundings. That is, both the system and the surroundings are returned to their initial states at the end of the reverse process

口自发过程( Spontaneous Process) 不需要任何外界作用而自动进行的过程。 a process which can happy naturally without the interference from the surroundings
